WebProeutectoid ferrite can form in steels when the carbon content is lower than the eutectoid composition (hypoeutectoid steels). Likewise, proeutectoid cementite typically forms in steels when the carbon content is greater than that of the eutectoid composition (hypereutectoid steels) (see Fig. 7.1).For plain carbon steels, i.e. Fe-C-based alloys … WebThe ferrite which is incorporated in pearlite is called eutectoid ferrite, whereas, the cementite present in pearlite is called eutectoid cementite. In this alloy (0.4 % C steel), the proportions of ferrite and cementite (just after the eutectoid reaction) can be obtained directly by applying the lever rule as: richmond american homes anika https://jfmagic.com
